<P>PROBLEM TO BE SOLVED: To accurately inhibit a tailing room entry for preventing a person from fraudulently entering a room without permission through a door opened by a person with permission, in a tailing room entry inhibiting control system. <P>SOLUTION: A tailing room entry inhibiting control system comprises: a tag ID reading means for reading a tag ID of an RFID tag carried by the person permitted to get into the room; a number-of-tags counting means for counting the number of tags by counting the number of the read tag IDs read; an image range limiting means for limiting a range of an image obtained by imaging a room entry place of the person permitted to get into the room, so that the range of the image can correspond to a RFID-tag communicable one; a means for counting the number of persons imaged by counting the number of the persons in the limited image range; a counting result comparing means for performing comparison so as to determine whether or not the number of the tags corresponds to that of the persons; and a door opening/closing control means for controlling the opening/closing of the door so as to enable the opening/closing of the door when the number of the tags corresponds to that of the persons, and to disable the opening/closing of the door when the number of the tags does not correspond to that of the persons, as the result of the comparison. <P>COPYRIGHT: (C)2008,JPO&INPIT |
